The San Francisco Giants’ closer situation took an unexpected twist yesterday, after the series against the Colorado Rockies concluded. Sergio Romo, who was removed from the role over a month ago after a string of poor performances and blown saves, is now back in contention. The move more likely reflects Romo’s recent success as oppose to the shortcomings of Santiago Casilla. Bochy revealed after the game that he will now opt for a closer by committee.
Romo has been brilliant of late, Casilla on the other hand – not so much. While Santiago is having another brilliant season, his inability to perform in high leverage situations and his recent high walk percentage will now force him to share closer duties. This season, in situations classified by fangraphs as high leverage, opponent batters have hit a rather too high .246 off of Casilla, in comparison to the .130 batting average in low leverage situations.
In the month of August Casilla has a 4.15 ERA with a 4.05 FIP. The numbers aren’t detrimental and in no way take away from the brilliant season he has been having, they do, however, call for some concern. Thus, Santiago, the hard-throwing right hander, will now only be put into save opportunities when the splits favor him.
Romo has been excellent in the month of August. In eight and two third innings, Sergio has yielded no runs, held opponents to a batting average of .174 while striking out 13 batters. Rather impressive. Consequentially, Romo has fought his way back into consideration for the closer role from now on. While most chatter regarding closer is centraled round Romo and Casilla, left handers Jeremy Affeldt and Javier Lopez are likely to be in consideration too, if the splits favour them.
